Hi everyone. I am new to this forum and I just bought a 2002 Vulcan 750 with 10500 miles :pepper:.
I will need to change the tires on it and I was reading about the drive shaft problems (I hope mine is still in one piece and there is some grease there).
I do not know a lot about the Vulcan in general but I am learning something new every day. I want to do a tune-up to the bike (spark plugs, balancing the carbs, brakes, fluids etc.) - I do that with everything I buy.
I saw that the bike has 4 spark plugs but it only has two cylinders. 2 spark plugs / cylinder is ok with me :D
Are all the spark plugs the same? If not, Is one cold and the other one hot?
I some posts the NGK DPR7EIX-9 saprk plug was mentioned. What do u think about them?
Thanks

They are the same plugs all the way around and the NGK's are the best IMO

The only thing with the wires is you do not want the resistor type wire. 7mm copper core silicone jacket is more than adequate for a stock ignition system. If you cannot find it at your local parts store Ron (Lance328) has it for sale.

Here is a link to the verses with info about plugs and wires.
http://www.vn750.com/forum/showthread.php?t=1162

Check with lance328 if you think you need plug wires, as I believe he keeps the NGK components in stock, and at a better price than elsewhere.

Somebody posted a year or so ago that he got wires cheap, off a Volvo in the auto wreckers, that are copper core and non-resistor, and worked well on the vn.

Thank you guys. I will check the local parts store for the wire and then go from there.

Another question regarding maintenance... How often do u change the cooling liquid, shaft drive oil, fork oil, balance the carbs etc?

I usually change the oil every 3000 miles, at the end and the beginning of the season. I usually balance the carbs at the beginning of every season.

I never owned a liquid cooled motorcycle so I have no idea regarding this. My last motorcycle was a 1981 GS450 that I purchased 3 years ago (I rebuild the engine, carbs, repaint, redid electrical, brakes, forks, shocks etc) and I traded that bike + $$ for the Vulcan.

I`m glad that I can help someone else right now, because I have to lay in bed or my easy boy chair for the next two weeks with my leg supported higher than my heart to keep the swelling down, after the surgery 12 days ago. If it wasn`t for this forum I would have gone stir crazy a long time ago.

Joe, what is the difference between the Fiamm El-Grande horns you have in your sig line, and the Freeway (or maybe they are called Highway) Blasters. I can`t find the El-Grande`s listed anywhere.

If you get a service manual, there is a table with a service schedule for what needs to be done and how often, in mileage or time.
There is a free, downloadable vn750 manual here: http://www.tocmanufacturing.com/Products.htm

Scroll down to "Other Links", and the manual is the first link.

from what i have seen of the highway blasters they look the same I think it is just packaging.

NightRat, you shouldnt have to sync the carbs as long as you havent messed with the sync screw. These carbs are pretty good for that, I've known people that have never needed to sync CVK's.

GET THE IRIDIUMS! lol Trust me, I could definitely tell a difference right away when I switch to the Iridiums from the stock NGK plugs.

Where did you mount them? The studs on my Blasters are too short and too large in diameter to fit the bushings in the rubber mount dampers on the Vulcan. I`m thinking about mounting on the neck side covers, but not sure they will fit without interference.:confused:

I mounted them with the brackets and attached one to each side pointing forward from the holes left from the earshave under the tank.

Are these IRIDIUMS a brand or a type of plug?

They are a type of NGK plug
Ididium and platinum are precious metals that are very hard and resistant to electrical erosion.
A small piece is welded onto the tip of the center electrode of the plug, which may last for 100K miles.

Night rat if you check the threads about spark plugs you will see that a lot of us are using the Iridium plugs. They give you a better start cold or hot. Just something you should check up on if you have trouble with hot starts at least.
